Hi /prog/, I have some experience with C, but I don't know how to do much except take text input, save variables, calculate, and print text out. What should I read to learn to do things like display graphics, save/load files, send/receive data using ports, et cetera?
save/load files
wait, you know how to ``print text out'' but you don't know that?
You need to read about file I/O. when you ``print text out'' you're basicly using some file IO operation to write to stdout.
send/receive data using ports
well first you gotta clear that concept in your mind before you attempt to write some socket I/O program. i recommend teh TCP/IP protocl
display graphics
use some 3rd party library/etc like wxWidgets, GTK, Qt and friends.
